hi K., first of all, i totally agree with eveything jc said, sounds like those kids are too old at the very least, i cant see how much good can come of it. ,,, so, a few weeks ago, my 6 year old, michael, came home upset because a kid in his class told him he hates him, and he has absolutely no idea why. michael is very quiet in school, i asked him what he did to this kid, he said nothing at all, seems genuinely bewildered. we dont even use the word hate in my house. well, my husband and i were both really very surprised by how upset we both were. how could somebody possibly not like my little angel, GASP! i felt like mrs seinfeld,lol... anyway, what we did was to just use it as a teaching opportunity. we talked to him a lot about it, casually. told him that some kids just might not like you, not everyone likes everyone. told him to be sure that he does the right thing, that he is polite. discussed how he should handle it if the kid starts to give him problems, how to calmly stand tall and stick up for himself. told him that sometimes kids are mean to other kids because they feel bad about themselves or something in their lives, and/or maybe he just doesnt know how to be a friend yet. or maybe he just doesnt like you, and its really not your problem. let me know if he bothers you, stand up for yourself if you need to, but dont worry about it otherwise. you have friends and they are the ones who matter, the kids who treat you well. this conversation did not take place all at once, btw, little bits here and there, and i really tried to be casual about it. and i did ask the teachers if anything was going on, they said not at all, they are aware of what was said and will keep an eye, but so far nothing. give your son plenty of opportunity to play with other kids, and have conversations about what it means to be a friend. i even threw in a casual staged phone call so he could "overhear" me talking about how i dont really bother with so-and-so (no one he knows) because she doesnt treat people well. helps him to learn how to treat others and how he should expect to be treated. also, he has gotten friendly with our neighbor, the kid is ok, but has been mean to my younger 2 kids a few times. i told michael that first of all, nobody gets left out, and secondly, if this boy is mean to anyone in our family, you should try to teach him to be nice, he just might not get it yet. and if he still cant be nice, he cannot play here. set your standards now, and give him the confidence to have standards too. its just the beginning.
